Comparison between two simulations with identical jet power but differing intrinsic parameters – jet radius, velocity, and magnetic field – highlighting their impact on the spatio-temporal evolution of the jets (left: ‘highB_min85’; right: ‘lowB_varRV_min85’). The top two rows show density slices (at z = 0), illustrating the larger-scale jet morphology over an extended evolution period. The bottom row presents corresponding Lorentz factor slices, emphasizing jet-beam’s (de)collimation and thrust in shaping different classes of radio galaxies.
